Italian brand Acca Kappa have been creating luxury bath and beauty products for over 50 years (most commonly seen in Four Seasons Hotel suites worldwide). But in celebration of their 140 year history, they've created a limited edition toothbrush that is hand cut, milled and handle shaped from biodegradable cellulose acetate with natural bristles. The cellulose is non-toxic and transparent, and biodegrades at the same rate as that of an oak leaf.

We first saw this toothbrush at Anthropologie ($5.50), along with other biodegradable personal hygiene items like this body brush ($54), hair brush ($36), and comb ($15). After doing a little searching, we also found the toothbrush available through Amazon for $5.99.
